In this post, the author discusses their weekend project of building a simple load balancer, a crucial component in large-scale systems that evenly distributes requests among multiple servers. This is essential for effectively handling a high volume of requests. The author uses an example of deploying five instances of an application instead of one to illustrate scalability; rather than a single instance managing a million requests, each instance only handles 200,000 requests, reducing the risk of failure. To distribute those requests uniformly among the instances, the

The passage discusses a well-known puzzle involving an infinite grid of resistors arranged in a square lattice, where each pair of adjacent nodes has a resistance of R. The goal is to determine the effective resistance between two adjacent nodes. The usual approach involves analyzing the current flow from one node to its neighbor and vice versa. By considering the symmetry of the current flow fields and adding the contributions from each node, it can be inferred that the effective resistance between two adjacent nodes is R/2. This mirrors concepts

The author prefers Postgres for new projects due to its flexibility and support for various performance scenarios, particularly highlighting the importance of Transactional DDL (Data Definition Language). Unlike MySQL, Postgres allows multiple database schema changes in a single transaction, rolling back all changes if any fail. This capability is especially beneficial when using migration frameworks like PlayFramework with Evolutions, where up and down scripts can be applied. However, down scripts are often untested, leading to potential issues where they don't correctly reverse
